The Secret Swimming Tanks of D-Day

Today, we remember the courage, sacrifice, and determination of the thousands of Allied soldiers who landed on the beaches of Normandy on June 6, 1944. D-Day was one of the largest amphibious invasions in history: over 150,000 troops, thousands of ships, and tens of thousands of vehicles were deployed in a mission that helped change the course of World War II. Among the most ambitious innovations of the invasion were the "Duplex Drive" Sherman tanks—35-ton armored vehicles specially modified to float and swim through rough seas before reaching the beaches. Designed to give Allied troops critical armored support during the assault, these remarkable machines represented both the ingenuity and the immense risks of Operation Overlord. In War Wrecks: The Lost Tanks of D-Day, historians and underwater archaeologists investigate the fate of these extraordinary vehicles and uncover one of the most fascinating stories hidden beneath the waters off Normandy. On this D-Day anniversary, we honor those who served and sacrificed, and remember the courage that helped shape history. Watch War Wrecks now on Curiosity Stream.
